摘要

与传统的二元差分NRZ信号相比，相关非归零(CNRZ)信号具有更好的引脚效率，同时不影响对符号间干扰(ISI)的敏感性。本文分析了CNRZ收发器的性能，并提供了采用FinFET 16nm技术实现的20.83 Gb/s/线超短距离(USR)链路的实验数据，该链路消耗1.02 pJ/b。由于CNRZ基于正交变换，编码和解码都可以在模拟中进行，而不需要任何延迟成本。

Short-Reach and Pin-Efficient Interfaces Using Correlated NRZ

Correlated Non-Return-to-Zero (CNRZ) signaling exhibits better pin-efficiency compared to the conventional binary differential NRZ signaling, while it does not compromise the sensitivity to Inter-Symbol Interference (ISI). This article analyzes performance of CNRZ transceivers, and provides experimental data for an Ultra-Short Reach (USR) link at 20.83 Gb/s/wire, implemented in FinFET 16 nm technology, consuming 1.02 pJ/b, As CNRZ is based on an orthogonal transformation, both encoding and decoding can be performed in analog, without any cost in terms of latency.
